Subject: [PATCH v2 06/10] mmc: meson-mx-sdio: Depend on OF_ADDRESS and not just OF

Making COMMON_CLK a visible option causes the sparc allyesconfig to fail
to build like so:

   sparc64-linux-ld: drivers/mmc/host/meson-mx-sdio.o: in function `meson_mx_mmc_remove':
   meson-mx-sdio.c:(.text+0x70): undefined reference to `of_platform_device_destroy'
   sparc64-linux-ld: drivers/mmc/host/meson-mx-sdio.o: in function `meson_mx_mmc_probe':
   meson-mx-sdio.c:(.text+0x9e4): undefined reference to `of_platform_device_create'
   sparc64-linux-ld: meson-mx-sdio.c:(.text+0xdd4): undefined reference to `of_platform_device_destroy'

This is because the implementation of of_platform_device_destroy() is
inside an #ifdef CONFIG_OF_ADDRESS section of drivers/of/platform.c.
This driver already depends on OF being enabled, so let's tighten that
constrain a little more so that it depends on OF_ADDRESS instead. This
way we won't try to build this driver on platforms that don't have this
function.
